No! With WhoDunnit Dinners everyone is in the dark, including the murderer themselves! Argueably this is less 'true to life' but in our experience it makes for a more interesting evening, if everyone thinks that they might be guilty. All the guests are then looking out for clues as to who committed the crime. (You can also accuse yourself - or throw yourself on your sword - in the Accusations Round, if you think you were the only one who had the means, motive and opportunity!)
